Bushmaster SnakePictures of Bushmaster Snakes The Bushmaster, lachesis muta muta is the largest Pit Viper in the world with a nasty reputation as a "cruel dude". The Bushmaster is a huge, thick-bodied and highly venomous snake with a triangularly shaped head, one of nature's warning signs that a snake is poisonous and potentially deadly. Bushmasters live in remote, heavily forested tropical jungle terrain. Isolated in their jungle environment, envenomation by a Bushmaster is very serious, sometimes fatal and particularly dangerous to humans.
